本文件规定了多传感器点式火灾探测器的要求、试验方法和性能标准，这些探测器包括烟雾传感器、一氧化碳（CO）传感器和一个或多个热传感器（可选），用于建筑物中安装的火灾探测和报警系统（见ISO 7240-1）。 对于使用不同原理的烟雾、一氧化碳和可选热传感器测试其他类型的火灾探测器，本文件仅供参考。本文件不适用于使用烟雾、一氧化碳和（可选）热传感器的火灾探测器，这些传感器具有特殊特性，并且是针对特定风险开发的。

This document specifies requirements, test methods and performance criteria for multi-sensor point fire detectors that incorporate a smoke sensor, a carbon monoxide (CO) sensor and, optionally, one or more heat sensors, for use in fire detection and alarm systems installed in buildings (see ISO 7240？1). For the testing of other types of fire detectors using smoke, CO and, optionally, heat sensors working on different principles, this document can be used only for guidance. This document is not applicable to fire detectors using smoke, CO and, optionally heat sensors, which have special characteristics and which have been developed for specific risks.
